Abstract (en)
[origin: US2019267845A1] Systems and methods are provided herein for providing wireless power from a wireless power transmitter. The transmitter includes a rectifier comprising a first coil coupled with a second coil and a switch having a first switch state and a second switch state and an output electrically coupled to a node between the first coil and the second coil. In the first switch state, the rectifier is configured to output a first current having a first polarity through the first coil and a second current having a second polarity through the second coil, the first polarity and the second polarity are different. And in the second switch state, the rectifier is configured to output a third current having a third polarity through the first coil and the second coil.
